This picturesque city encompasses the 365 islands – 49 are inhabited – of the sprawling Yeosu peninsula on South Korea’s East China Sea coast. Historically critical as headquarters of the Korean navy during the Joseon (Yi) dynasty (1392–1910), Yeosu underwent a dramatic modernization when it hosted the 2012 World Expo and today offers a blend of verdant hills, glistening seas and striking architecture. Yeosu is a renowned foodie haven, with restaurants serving traditional fare like egg cockles, gulgui (grilled oyster) and spicy kimchi made with locally grown mustard leaves.
